On-Demand, Link-State, Multi-Path QoS Routing in a Wireless Mobile Ad-Hoc Network

چکیده
In this paper, we investigate an on-demand, link-state, multi-path QoS (quality-of-service) routing protocol in a MANET, which is important for many real-time multimedia applications. The basic idea of the on-demand, link-state, multi-path routing protocol is to reactively collect link-state information from source to destination in order to dynamically construct a partial network topology which is only sketched from source to destination in a MANET. Therefore, a multi-path QoS routing protocol is proposed by finding multi-path routes at the destination under the CDMA-over-TDMA channel model, which satisfies a given bandwidth requirement. Existing work mainly aims to exploit a uni-path from source to destination. The destination accurately determines a QoS multipath routing and replies to the source host. This greatly improves the success rate by means of searching the QoS multi-path routing. Performance analysis results demonstrate that our proposed protocol outperforms other protocols.

Improving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...

In recent years, on-demand routing protocols have attained more attention in mobile ad hoc networks as compared to other routing schemes due to their abilities and efficiency. There exist many ondemand routing protocols for Mobile Ad hoc Networks (MANETS). Most of the protocols, however, use a single route and do not utilize multiple alternate paths. Multi path routing allows the establishment ...
